Facilities
We are equipped with a modern infrastructure to reproduce tribological systems that are found in industrial applications. We also have facilities for corrosion-erosion testing, friction welding processes (Friction tapered plug welding) and depth-sensing indentation. This infrastructure was developed through partnerships with the private sector and by developing R&D projects with the support of government agencies.
Following, some of our research facilities are listed. If any special field test conditions are required, we offer the possibility of developing and constructing new facilities to fulfill your demands. Do not hesitate to contact us.
